Monitored & Set Conditions
WARNING: This page is about a different car, the 2004 Chrysler Intrepid, 2003 Dodge Intrepid, 2003 Chrysler Intrepid, 2003 Chrysler Concorde, and 2003 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
This code is monitored with the engine running. Fuel level greater than 12 percent. Ambient temperature between 39-89°F (4-32°C). The code is set when the PCM does not see the NVLD switch close during the medium/large leak test. The PCM will then increase the vacuum supply to the EVAP system by increasing flow through the EVAP purge valve. If the switch does not close with an increase in vacuum, an error is detected. This is a two trip fault.
